    We've all heard about how lightning can produce enough energy to power NYC for like a year. With all the lightning strikes that happen all over the world, I view this as a massive waste of electricity that we could use.

    Obviously the challenge to this is storing that much power, but I think it could be done. What do you think?

    I've been thinking about this too.
    Just google it and you'll find a lot of people made this analysis: while the energy is powerful, the fact that a lightning just strikes for 0,025sec makes the total amount of energy very limited (I've seen numbers around 140Kw/h). 2 difficult problems remain: how to know where the lightning will strike, and how to harvest it.
    As an example: Harvesting lightning energy - Wikipedia, the free encyclopedia.
    Anyway where do this statement come from (power NYC for a year)? Is it achieved by harvesting all the US territory lightning for 1 year too?

    Let's see if it really worked on 21/10/2015! (for the atheists, the date they time travelled in the future). :scared:
